Yelocate improves WooCommerce checkout by validating customer addresses, email addresses, and phone numbers in real time using an external validation API.
The plugin works by collecting checkout field values in the browser and sending them to a server-side AJAX handler in WordPress. The handler securely calls the configured validation API and returns a normalised response displayed to the customer as an inline banner near the relevant field.
Each validation type (address, email, phone) can be enabled or disabled independently and configured with its own CSS selectors, so the plugin adapts to any checkout layout — classic WooCommerce or block-based.
<h3>External Services</h3>
This plugin connects to the Yelocate API (https://yelocate.com) to perform 
real-time validation of addresses, email addresses, and phone numbers at 
WooCommerce checkout.
What data is sent and when:
<ul>
<li>Address validation — billing address fields (address line 1, address 
line 2, city, state/province, postcode, country) are sent to the API when 
the customer fills in their billing address at checkout. Only triggered for 
the 40 supported countries listed below; all other countries are silently 
skipped.</li>
<li>Email verification — the email address entered in the billing email 
field is sent to the API as the customer types.</li>
<li>Phone verification — the phone number entered in the billing phone 
field, along with the billing country code, is sent to the API when the 
customer leaves the field (on blur), provided at least 7 digits are present.</li>
</ul>
Each validation type can be independently disabled. No API calls are made for 
disabled validation types. The API key is stored server-side and is never 
exposed to the browser.

<h3>Features</h3>
<ul>
<li>Address validation — verifies billing address in real time; detects missing components, suggests field-level corrections, and silently skips unsupported countries</li>
<li>Email verification — validates deliverability and detects disposable or malformed addresses as the customer types</li>
<li>Phone verification — validates phone numbers on blur once at least 7 digits are present; passes the billing country as the region code for accurate international validation</li>
<li>Server-side API calls — the API key is never exposed to the browser</li>
<li>Works with both classic and block-based WooCommerce checkout</li>
<li>Each validation type has its own configurable CSS selectors and banner mount point</li>
<li>Per-type enable/disable toggles — only enabled validations trigger API calls</li>
<li>Intelligent address diffing — for suggested addresses, the plugin compares entered vs. suggested values field by field; if the only differences are formatting or language conventions, the address is treated as valid</li>
<li>Graceful handling of incomplete addresses and unsupported countries</li>
<li>Fully configurable via WordPress Admin → Settings → Yelocate Validation</li>
</ul>
